or NRW SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 292,993, datedFebruary, 1884.

Application filed June 20, 1881. (No model.)

To all whom it may concern.:

Be it known that I, LUTHER O. ORownLL,

a citizen of the United States, residing in the city of Brooklyn,countyof Kings, and State of New York, have invented certain new anduseful Improvements in Sheet-Delivery Apparatus for Printing-lvlachines,fully described and represented in the following specification and theaccompanying drawings forming apart Io of the same.

The object of my invention is to produce a machine by which a web ofpaper can be printed, cut into sheets, and the same delivered foldedeither as single sheets with or without a supplement folded in each, oras two sheets superposed with or with out asupplementsheet; and theinvention onsists of the combinations of parts in such a machine, aswill be hereinafter fully described and claimed.

In'the drawings, Figure 1 represents a side elevation of a machine inwhich the present inventions are carried out. Fig. 2 is a plan view ofthe same. Fig. 3 is a verticallongitudinal section of the same on theline m of Fig. 2. Fig. 4L is an end view of the same, the

printing mechanisms being omitted. Fig. 5 is` i an end View yof thegathering or collecting cylinder by which sheets are superposed whilemoving onward. i

In these drawings,A and B represent the last pair of the well-knownweb-printing mechanism, the impression-cylinder A and-the typecylinder Bbeing journaled in the frame 9 of the machine. In advance of thesecylinders there is a roller, 8, journaled in standards that rise fromthe frame 9, over which roller the printed web is led.v A rotary cutteror slitter, is secured to a shaft that is also journaled in saidstandards, which cutter is ar- 40 ranged to bearupon the roller 8, whileboth the roller and shaft are free to revolve in their bearings. Asheet-turner, 4.6, in this instance constructed substantially as isdescribed in Patent No. 181,250, dated August 22, 1876,

+5 depends from a bar, 4f', that is secured to the side frames. Inadvance of these parts there l is a cylinder or carrier,v O, the shaftof which is jonrnaled in bearings in the frame 9. rlhis cylinderhasjournaled near its p criphery, in a foldingblades, 20. One end of thisshaft projects beyond the end of the cylinder O, and is provided withfour equidistant lever-arms, 68. (See Fig. 5.) A portion of this shaftbetween the arms 68 and thehead of the cylinder C is made square, andupon this squared portion a spring, 66, secured to the end of thecylinder, is arranged to bear and act as a stop for `the shaft, to holdit in any position to which it has been turned. Opposite the recess inwhich the shaft 18 is hung is another recess in the cylinder O, in whicha shaft, 24, having its bearings in the ends of the cylinder, isjournaled. This i shaft is provided with two or more pins, 25, forentering and holding the paper, and at or near one end with a crank, 27,to which a con; nectingrod, 28, is attached, said connectingA rod inthis arrangement passing through an eye in a bearing-block, 51, attachedto the end ofthe cylinder, and it is provided with a col l lar, 29,between which collar and the said bearing-block 51a spiral spring,Asurrounding said connecting-rod, is confined. The outer end ot' thisconnecting-rod is rounded and projects slightly beyond the periphery ofthe cylinder O for a purpose to be explained. Projecting over one edgeof the recess, opposite the'shaft 18, is a serrated cutting-blade, 26,provided with apertures 21, through which the pins 25 may work. On theopposite side of this recess is a springplate,23,the function of whichis to hold the paper while it is being cut against the cutting-blade,(to be described) that ccacts with thecutting-blade 26 iii performingthe cutting operation. Another cylinder, D, the shaft 30 of which isjournaled in the frame 9, carries devices that co-operate with those ofthe cylinder O. For a purpose that will presently appear this cylinder Dis made, as shown, `twice the diameter of the cylinder O. At pointsdiametrically opposite to each other the periphery of the cylinderD isprovided with. recesses, in each of which is journaled a rock-shaft, 5,having its bearings in the ends of the cylinder, to which' shaft aresecured two or more vii brating nippingjaws, 33. One end of each ofthese rock-shafts 5 projects beyond the end of the cylinder D, and `isthere provided `with a crank-arm, 40, having'a roller running in con 5orecess, a shaft, 18, carrying'four cquidistant` IOO frame 9. Thisstationary cam 41 is so shaped. as to cause the nipping-jaws 33, throughthe:

- that the end of the connecting-rod 28 :mayroll in contact therewithand be operated to rock the pins 25, and withdraw them from the paper atproper times, as will be hereinafter more fully explained. Thesecam-plates 34 are made capable of being removed from operative positiononv the cylinder D, as is illustrated bythe absence of one of thcminFig. 1. The cylinder D is furt-her provided upon its periphery with twooppositely-situated cutting-knives, 31 32, the serrated edge of each ofwhich works in connection with the serrated edge of the cutter 26, andwith it forms a cutting mechanism that will operate to sever the paper.The cylinders A B C D are all geared together, so that their peripheralsurfaces will run at a uniform speed,the usual gearwheels,101 102103,being supplied for that purpose with an intermediate to secure theirproper direction of travel.

The mechanisms operate in the following manner: If it be desired todeliver singlesheets each with an inset supplement, the endless web 50will be of a width sufficient to receive impressions of appropriatematter for the main and supplement sheets, and will be split on a linedividing the main and supplement portions by the cutter 7, 'after it hasleft the impression and type cylinders,and is passing between the roller8 and cutter 7, which slits it longitudinally and forms it into twowebs. The main portion of the web passes directly to the cylinder C,while the narrow or supplement portion 14is led from the roller 8 downand around thturner 46, and back up over the roller 8, (see Fig. 4,) itbeing by this operation transferred laterally, so as to be 'broughtbeneath and associated with the main portion of the web, with which itthen passes onto the cylinder C. The pins 25 on this cylinder C passthrough the leading ends of the asso-v ciated main and supplement webs,and carry said webs onto the cylinder and around with it, said websoverlying the recess in the cylinder and the folding-blade 2O thenslightly protruding therefrom. As the cylinders G D revolve and thefolding-blade recess in C and the jaw-recess in D approach each other, afolding-blade, 20, will be carried into the range of action of asct ofjaws, 33, which latter, being operated by the rock-arm 40, will,whilesaid arm is passing over the cam 41, be quickly moved upward and closed,in such movement sweeping within the folding-blade recess in thecylinder C, so as to engage and force the one of the folding-blades 20,then in operative position, outward beyond the periphery of the cylinderC and within the jaw-recess of the cylinder C, whereby the paper isengaged and are opened to release it.

1 about the moment when the jaws have commenced to act upon vthefolding-blade, as just described, the cam-plate 34 comes into contactwith the rounded end of the connecting- -rod 28, and rocks the pins 25within the periphery of the cylinder C, thus withdrawing Vthem from theleading edge of the paper and releasing it. rlhe paper held by itsdoubled i, part in the nip of the j aws, as j ust described, is carriedonto the surface of the cylinder D,

and when the folding is completed the jaws v In folding or doubling thepaper into the nip of thejaws, as j ust described, the folding-bladewill have been moved about one-eighth of a revolution, and, carryingwith it the shaft 18, it will have brought one of the rock-arms 68 intosuch a posi-tion that, as the cylinders C D revolve, said lever or arm68 will strike a tappet, 69, that is secured to the frame 9, and berocked so as to cause the shaft 18 to turn far enough to complete aquarter-revolution, in making which the folding-blade is withdrawn fromthe p doubled part of the paper At the end of this movement of the shaft18 the spring 66 bearsupon one of its squared sides and suspends andsecures the shaft in that position until it is again turned in theoperation of folding the paper, the folding-blades then standing withinthe periphery of the cylinder C, as in Fig. 1, with one in position tobe engaged by the folding-jaws in the next folding operation. The paperheld by its doubled portion in the jaws of the cylinder D will becarried onward with that cylinder, and when the cylinders have so farrevolved as to bring the serrated edge of the Aplate 23 opposite theserrated edge of the plate 32 (or 31, as may be) said plates willarticulate and cause the paper to be severed, during which operation thepaper will be held by the flexible plate 23 against the plate 32. Justbefore this occurs the paper just back of the` serrated edge of thecuttingblade 26 is again impaled upon the pins 25', which have beenrocked outward by the action of the spring 100, as soon as the cam-plate34 was carried out of contact with the rod 28.

The paper, while held by its doubled edge in the nip or bite of the jaws33, may be released at anytime after the severing has taken place, asabove described, by properly shaping the cam 41, against which therocking arm 40, attached to the shaft carrying said jaws, works.

The operation just described is repeated at each revolution of thecylinder C, both camplates 34 being adjusted in working position,

both jaws 33 being in operation, and the cuttingblades 31 32 alternatelyoperating in connection with blade 26, and thus papers are deliveredwith a supplement folded within them. If desired, further folds may bemade in the transversely-folded paper bypany of the well-known devicesfor folding paper.

If it be desired to deliver papers each consisting of two sheetssuperposed and folded together without asupplement, and with differentreading matterupon each of their pages, the first type-cylinder, as wellas the last, A, mustbe increased in size, in order to carry therequisite number of printing plates or forms, as is well known. One ofthe cam-plates 34 will then be removed, as in Fig. 1, or renderedilroperative in any common way, and one set of j aws, 33, will also berendered inoperative in any coinmon way, as byremovin g its arm 40. Theweb of paper, of a width equal to the length of the folding-blade, orless, as may be desired, passing from thelast impression and typecylinders B A over the roll 8 and cylinder or carrier C, is impaled uponthe pins of the cylinder C, and carried by such pinsas the cylinderrevolves until the cutting blade 26 severs the web.

' Just before this cutting takes place the web is preserved during thesubsequentmanipulation of such sheets. On this second revolutionofthecylinder C the set of jaws 33 65, that have not been thrown out ofoperation, coming opposite one "of the folding-blades 20, cause it totuck the fold-line of the sheets between said jaws, as vbeforedescribed, and as soon as the jaws have grasped the doubled portionofthe sheets the cam 34,1which'has not been removed or thrown out ofoperation, coming in contact with the rounded end of the connecting-rod28, causes the pins 25 to be withdrawn within the cylinder, thusreleasingthe leading endsof the sheets. Upon the further revolution ofthe cylinders C D the second cutting-plate 32, operating-in connectionwith the cutting-plate 26 on the cylinder C, again severs the web, thepins 25 having just previously to this cutting been again projected bythe spring, and these pins again have hold of the leading edge of theweb, The

two sheets, superposed with their double porleading the supplement webin under the main -web after the latter has been severedand turned 5 butin this case two slitters will have vto be used and a web-guide toproperly direct the supplement web.

W'hen it is desired to paste the supplement and main sheets constitutingthe signature together. it may be accomplished by any of the well-knownpasting devices.

It is evident that the `printed paper may be led over or through alongitudinal folding mechanism like any shown in patents heretoforegranted to me, or substantially the same in mode of operation, and thento the cutting and folding devices shown herein; orthislongitudinalfolding may be applied to once-folded sheets.

The sheet-registering pins may be applied to any form of gathering orcollecting mechanism wherein two or more sheets are associciated-sueh,for instance, as are shown in Letters Patent Nos, 192,510, 192,954,191,494, 197 ,693, 253,325, bor the patent granted to me May l, `1883.

Although means for associating webs, first laterally and afterwardlongitudinally, (as by` bringing different portions oflaterally-associated webs together through a collecting mechanisni,)and, in conjunction therewith, means for slitting a wide weblongitudinally to` produce narrow webs, and-cutting devices to sever thewebs transversely toiproduce sheets, and mechanisms for folding saidsheets transversely and the sheets or webs longitudinally, are eithershown or described herein, the same are not claimed herein, but are madethe subjectmatter of another application `filed June 22, 1883.

rlhe following is therefore alone claimed:

1. A cylinder or revolving carrier provided with means for gathering orcollecting sheets, and with pins for securing a proper register of thesheets, substantially as described.

2. The combination, with a rotating carrier provided with nipping-jaws,of a carrier provided with means for gathering or collecting sheets, andwith a folding-blade co-operating with said jaws, all substantially asdescribed.
